LPSC (Li5.5PS4.5Cl1.5) is a highly promising sulfide-based solid-state electrolyte (SSE) belonging to the argyrodite family. It is a chlorine-rich, lithium-deficient derivative of the parent argyrodite Li6PS5Cl. This specific composition is of great interest for all-solid-state lithium batteries (ASSLBs) because it offers a rare balance of high ionic conductivity and favorable electrochemical stability.
